Specification of Letters Patent.

Be it known that I, GARRY J. Dommuvnr,

folding theedges of cell orcollar blanks or analogous articles, and more particularlv to that species of infolding machine comprising in combination a bed or support l'orsupporting fabric blanks, a member or templct having substantially the outline of the finished article and adapted to define the folds to be formed in the blank, and movable infolders having actuating mechanism for causing them to move inwardly to carr) the edges of the fabric blanks over the edges of the tcmplet, and outwardly. i

The various features of imirovement described and claimed in the following specification are shown as applied to an infolding machine which may be driven by power as distinguished from hand operation, and the particular machine shown and described is one in which the templet is composed of a plurality of relatively movable defining plates and in which the infolders are con-v neeted with pressing mechanism by which the folds of the blanks can impressed and creased between the infolders and bed after the extraction or withdrawal of the plates of the templet from such folds. The said features enabling the machine to be run by power constitute an. i mportant partof my invention, although many features may be employed wither without the power actuation.

It will be understood that when a blank for a cuff or other article has been infolded at its edges so as to conform to the shape of the templet, said blank together with a similar one or a mate thereto produced in an analogous manner, will be stitched together around the edges to form a completed cuil or other-article.

One feature contained in the hereinafter described machine is that of producing the diil'erent folds of a single blank alternately or successively in the ieculiar manner described, so that the f0 ds last formed. will overlap those first formed, thus producing What IS known as a lock corner; and the par- Patented. June 8, 1909.

Application filed June 15, 1897. Serial No. 640,817.

ticular mechanism shown is such that one blank may be folded n one manner and a succeeding blank wlth the edges produced in a reverse order, by which arrangement two blanks produced upon the same machine may be interlocked with each other and anchored prior to the stitching opcrationf T he above mentioned and many other features including those which relate to the capability of being operated by power, will be hereinafter described and claimed.

1 will first describe one particular embodimcnt of my invention, namely that shown in the drawings hereof, and will thereafter set-forth in the claims the novel features thereof.

Amrompanying this specification to form a part of it there are nine plates of drawings containing twenty figures illustrating my invention with the same designation of parts by letter reference used in all of them.

Of those illustrations, Figure 1, is a perspec tive of a machine containing my invention, showin; the position of the operator when applying blanks and when operating the foottreadle and clutch. Fig. 2, is a side elevation of the machine taken at that side of the latter which is opposite to that at which power is applied, with a part of the templet arm omitted.

Fig. 6, is a top view of the bed of the machine. Fig. 7, is a top view ofthe bed, with the infolders, the latches and the templet carrying: arm omitted. Fig. 8, is a side elevation of the clutch, the bar which operates it, the

slide-pin of the clutch-gland, and a. part of the shaft on which the clutch is mounted. Fig. 9, is a side elevation of the same parts that are shown at Fig. 8, taken at the side 0 posite to the latter, and with the clutchg and omitted. Fig. 10, is a section taken .on the line 3 11 of Fig. 9, and Fig. 11 is a section taken on the line y, y". of Fig 10, with-thewheel containing the clutclngland shown, as having made half a revol tion from the position in which it is shown at, Fig. 10. Fig. .12, is a vertical section taken through one of the cam-rollers on the camroller shaft (of which there is one o uch Pom rollers at each end of the shaft madealike) and through the mechanism with which the cam rollers immediately connect. Fig. 13, is a section taken through a part of the bed, the catchring, the segment-ringthe annular groove formed in the latter, and the annular slide-way formed in the bed for the. catch- -ring and the segment-ring, with one of the front segments within the segment ring and shown in end elevation; illustrating also one of the latches in side elevation, as disengaged from the bed. Fig. i l, shows the same artsthat are shown at Fig. 3, but with the .atcli operated to engagewith the bed. Fig. 15, is a top view of a part of the bed, one of the segments and one of the latches. Fig; 16, is a section taken through the bed with one of the catch-ring-catches shown in side elevation with the catch as down. Fig. 17, shows the same parts that are shown at Fig. 16, with catch-ring catch raised and. in a position to engage with one of the segmentlatches. Fig. 18, is a perspective oftwo collar blanks which have been infolded at their edges, so as to have the end infolds at the rectangular corners of one of the blanks, overlap the side infolds and the other-blank having its side inloid overlap the end inlolds at the rectangular corners by which the infolds thcreat may interlock, one within the other for connection when sewed. Fig. It), is a section taken on the line :5 of Fig. 4, and Fig. 20, is another section taken on the line a of Fig. 4.

The several. parts of the apparatus thus illustrated are designated by letter reference and the function of the parts is described as follows: I

The letters F, designate the frame of the machine, within and upon which the mechanism is mounted, and B, its base.

The letters B, designate the bed of the machine which is constructed with a chamber C,in which burning gas or steam is used and supplied by pipes 7) shown at F ig. l, the heating chamber being illustrated in section at 5.

The letter C, designates the driving-shaft which journals in the machine frame, and receives power from a pulley, P, mounted upon said shaft.

The letter G, designates a spur-wheel which is keyed to the driving-shaft, and this spur-wheel meshes into a gear-wheel G mounted to run loosely upon the shaft S,

when the latter is not operated by the connection which the clutch or gland-pin of the wheel W makes with the clutch-wheel C,

formed on the inner side of'the gear-wheel The letters It designate a 'canrroller mounted on and at one end of the cam-roller shaft S and the letter R designates another cam-roller which is also mounted upon the sa ami shaft S at that end of the latteuwhich is ppesite-te thatuimwhich is mounted the ca1n-roller R. his eamroller R, has formed in its )erimeter the encircling camgroove K, and this roller is com need of the two parts 1" and 2", both of \v ich are secured to the cam-roller shafts, S at one of its ends, with the cam-groove K, formed between said roller-parts as shown at Figs. 1, 3, 4' and 6;

The letters I63, designate a sleeve which is arranged upon the cam-roller shaft S between the roller-parts r and r, in which sleeve the cam-roller shaft turns.

The letter L, designates a lever which at its lower end is pivoted to thesleeve it, at w, and it is therefrom projected outwardly through the cam-groove K, to connect pivotallv by means of the short link Z, with the slide-bar lr. This slide-bar I), is provided with a slide-way in each of the sleeves E, which latter at each of their outer ends journal in one of the frame-parts F and at their inner ends they each make a threaded connection with one of the arms of the oke Y. By this connection, as the shaft S 18 rotated, the lever Ii,as pivoted to the sleeve it", engages altcrnatingl i with the opposite sides of the cam-groove Ii, and 'through its connection with the bar If, by means of the link Z it actuates' said bar to move reciprocals ingly in the sleeve E at 'm, and by the short arm fulcrum connectionf, which this lever L makes with the sides of the cam-groove K, the measure of its outer end movement where operating the bar I), is made greater than its short arm movement.

The cam-roller R is composed of the twoparts r and 1, between which there is formed the cam-groove K", arranged to encircle the roller, with said roller-parts connected to the shaft S at that end of the latter which is opposite to that at which located the camroller It. The letter 7c, designates a sleeve arranged upon the cam-roller shaft. between the roller parts 1' and 1- with said shaft adapted to turn in said sleeve. The letter L, designates a lever which at its lower end w, pivotally connects with said sleeve and therefrom is promoted outwardly to pass between the edges of the cam-groove K, to pivotally connect by means of a link 1, with the bar I), having, the slide-ways n, n, in the frame-parts F, F". As thus constructed when the shaft 5* is rotated its revolving cam-roller ll", by the connection which the lever L, makes with the sleeve 7;, and the bar I), will actuate the latter to move rcei IOCSttlilglYlll the slide-ways n, n, with the outer end ll, of the lever L, having a greater measure of movement than its short-arm Z. This slide-bar I), )ivotally connects with the segment-ring R l u, by which as said bar is reciprocated in its slide-ways the segment-ring is also reciproiy means of a bar or plate each of the segments and each of which slots ment to which it connects, ,PIOVKlCtl with a spring p, by which the Hillel" ends of each of the latches are forced upthe bed B and as will be more fully described hereinafter. i t V The bed ofthe machine as indicated at B", contains the annular shde way S", before named, and also the annular slide--.va'i S",

formed in the bed outside of the slide S and the letter C designates a catch-ring ada )ted to be reciprocated in the slide-way S, y means of a connection made with 'a switch-cam arranged in the perimeter of a' wheel mounted upon the cam-roller shaft S as will be more fully described hereinafter.

The letters A, A, designate two scgii'icnts arranged at the front of the machine within the groove g, made in the segment-ring it, and the letters A, A designate two segments arrangml in the groove 9, of the segmerit-ring it, at the rear of the machine.

These segments A, A, operate when latched to the segment-ring to move with the latter, while at the same time the seginei'its A, A", are latched to the lJOtl B, to remain stationary, when in succession the latter seginci'its become unlatclicd from the bed and latched to the segment-ring to move together with the latter, when the segments A, A, become unlatched from the segmentring and latched to the bed to remain stationary while the segments A A are moving. This alternating latching and unlatchtogether ing of the twosets of segments to the bed and I is accomplished by thethe scgni'cnt ring it, I following mechanism: The letters m desigmate a slot of which there is one formed in is eccentric to the arc of the circle in which the segments move. is i'ovidcd with a latch. I), which is jour- Iia ed between two ears 0'', e, which latter are upcast from the top of each of the segments; the lllllf'lllg or journaled connection of the latches between the. ears being made by the hinging-pin p, as shown at Figs. 13, 14 and 15. These latches, of which there is one for each segment, are made alike, and each of them on its inner end and under-side is pro-v vided with a downwardly projected pin 1); arranged to enter a sink p made in t 1c machine-bed 'B", when the segment is to be latched to the hed to remain stationary, with the segment ring in which the latched segments are placed tree to move in the groove or slide-way S". Each of' these latches L is arranged crosswise of the scgand they are each wardly away from the bed, with the outer ends running in' 'contact with the inner top edge of the seginent-ringtll,

excepting when the latches are being acted upon by the The letters Each of these segments ann uhir the latches, by which each of the latter will i he forced to drop into one of the sinks. I7 from the action of the spring p when the ,catch-ring catches unhitch the connection i made with the bed, and the segment-ring as l moving causes the sinks U to reach a point i beneath the latch-notches 0'. One of these latches as thus positioi'ied to latch one of the l segments to the segment-ring it", shown at t Fig. 13, and ft5 l1tttfll(?(l to the bed at. Fig. 14. The catch-ring C is arranged to he recip Z rocatcd in the annular slidc-wav S, formed in the bed B, outside of the segment ring slide-way, is provided with two catches c, (1", located at the rear of the apparatus, each of which is pivoted within a vertical slot made in the CtLtCl]l"ll1{I, which slot is designated at d with the pivotal connection designated at 0 as shown at Figs. i6 and 17". Each of these catches has an inclined up )er surface c, which when the catch is raise on its pivotal coni'iection will engage with the ,outer end of the latch upon the adjacent thereto when the segment has and by this engagement with the inclined top of the catch as moved by the catch-ring witi which it is connected, the outer end of the latch is raised. and its inner end forced downward] y against the recoil force of the spring 12 so as to have its pin p enter the sink p, which is next adacent, and thus each of the catches 0 acts to latch at the same time both of the segments A.

The. letters D, designate a plate arranged upon the underside of the bed B, beneath the catch-ring C and this )late D is provided. with inclines d (1, which as the catch ring is moving will simultaneously engage with the underside of the catches c, and so cause them to rise and thus bring their inclined surfaces each in a position to engage with one of the latches L noon each of the segments A to latch'them 0th to the bed by the engagement of their pins 12 with the sinks 1)", formed in the bed as before described, ments A A while the segment-ring ll", is moving to operate the segments A, A.

The letters 6, e, designate catches or in.- clines which are rigidly connected to the top of the catch-ring so as to move with the latter, andeach of these catches is i'ovidcd with an inclined upper surface eh hen the segments A, A, have been operated to move by being. latched to the segment-ring to the required extent of their movement,

ring C", caused to engage with the outer end of the segment latches connected to the segments A, A, to latch the latter to the bed as shown at Fig. 14. Thus by means of the catches e,'c, upon the catch-ring C the moving segment U reached the proper measure of its movement,

andthus hold stationary the segthe'inclines, c are by the action of the catch- I while the segment-ring moves; and the seg':

segments A}, A are actuated to connect with the bed, so as to remain stationary,

ments A A are actuated b the catches 0, 0 on the catch-ring as the latter reciprocates in its slide-way S to become latched and stationary while the segment-ring moves, and ,each of the latches on each pair of the segments A, r and A, A, as" the segment-ring moves when the latch-notch of each of the latches comes over the adjacent chine-bed, and each of these infolders I is ill rovided with a slide-bar V and a slidcwa P Vt. arranged on the machine-bed. Each of these slide-bars V of the infolders I, has projectodfroi'n its under surf ace a slide-pin v which is arranged to enter and have a sliding or cam engagement with the eccentric slot m formed in each of the segments A A, and each of the slide-bars V, oi the infolders I is provided with a slide-pin arranged on to. engage with and I tion ofthe machine-with the int'olders I I at rest, then the side edge infold produced by the infolders 1 will at the corners where rec its under surface to enter and make a cam or sliding engagement with one ol the eccentric slots m", of the segments A".

Each of the inl'olders l lflhas an L-form on its inner edge, and as operated together they are adapted when moved inwardly to conneetedly inlold one side and each of the ends oi a blank (liaving'whcre the ends and one side meet rounded corners) with the movement of these intolders inwardly and outwardly made'in a direction that is coruerwise to the inl'oldors and diagonal to the form of the blank being inl'olded. The inlolders 1. l, are also operatedto move outwardly and inwardly in a diagonal direction so as; tohave their end edges in alinement. with the ends of the inloldors i when -moved inwardly, and to thus produce upon the \blanh side edge on which they operated an inl'old haying rectangular corners. Each of the inl'oldcrs l'-, is connected to its slidcbar to have a small measure oi vertical movement in its slide-way so that it can be moved downwardly therein by the presserspress in the lnl'olds upon the bed. As thus made and arranged to be operated when the inl'olders 1 are actuated.

first by one revolution of the 'machine with the mloldors l at rest, and the nfolders l are then operated by a subsequent revolutangular overlap the end infolds; and when duced by the infolders I,

the order in which these infolders are actuated is reversed, then the infolds produced by the infolders 1 P, will at the rectangular corners overlap the side ed e infolds pro- With' the parts connected as thus described, when the segmentring R is reciprocatedin its annular slide-way at each reciprocation such of the segments as are latched to the bed will not operate the infolders with which they connect, but the ring will actuate the segments and their infolders which are not latched to the bed but are latched to the segment-ring; and by the arrangement of the catches upon the catch-ring C the infolders '1}, I, may be first dperatcd to then become hitched and then succeeded by the operation of the infolders I, 1 By this means blanks" thus having their. infolds made to oppositely overlap at their rectangular corners may be arranged to interlock thcreat, with the parts appearing as shown at Fig. 18, so that when stitched the blanks may be anchored one within the other at the rectangular corners. The letters T, designate the-templet which may be of any wellknown lorm though I prefer one having plates on its under surface which when expanded will have upon their outer edges the form of the blanks to be inl'olded. 'lhe tomplet herein shown is adapted to operate upon cull-blanks having upon one of its edges two rectangular corners, and upon the other side two rounded corners with parallel side edges between the corners. This lemplet is shown at Fig. .7, and 'is adapted-to be used with the inl'olders I, l,- and .1 l, shown, and of course corresponds in contour therewith.

The letters 1?, 15*, designate plates arranged upon lhennder sidc ol the tomplct stock N, and the letters 15,- t, designate two other plates also arranged upon the under side of the stock, and at. that side of the latter which is opposite to that on which the ilates t, t", are placed. The plates indicate at i have rounded corners, and the plates designated at If, have rectangular corners. Each of these plates i connects with the under side of a slide-ha r 11 and each ol' the, plates t" connccts'wiih the underside 01' a slide-bar n. Each of the slide-bars a is arranged to. be moved outwardly and inwardly .in a slideway 12 opening out lroui the side ol the stock on an angle; and each ol the slide-bars n is arranged to be moved outwardly and inwardly in a slid c-way a opening out from the side ol thcstock on an angle and at the side of the latter where the slide-bars a are located. The letter D designates a disk or wheel (indicated by adotted line at Fig. 7:) which is centrally pivoted at d, to the stock N, between t-he latter and the plate H, which latter is connected to the stock by studs d", and the letters Qh-Ofldesignate links, each of which at oneof its ends 0 is pivoted to the top of the disk D near its perimeter, and l wardly and horizontally to rigidly connect each-of which links at its other end is pivotally connected to one of the slide-barsn, operating the plates F, t to move outwardly and draw inwardly; and the letters designate two other links each of which at its inner end 0, is pivotally connected to said disk D near its rim with the other end of each of said links 0, each pivotally connected to one of the slide-bars n operating the tem-.

plet-plates t t and by which construction as said disk is reciprocated in rotation the templet plates t t and 1, i are moved outwardly and drawn inwardly. To operate this disk-wheel D-, to be rcciprocatingly rotated by power, the following mechanism is used: The letter l designates a lever which is horizontally projected reai'wvardly from one side of the disk D at its rear end, and this lever is provided with an' attached slide-pin U The letter E designates a sleeve provided with a groove g, and arranged on the bar 6 between the collars a, w, rigidly connected to said bar with the slide-pin U within the groove 9 of the sleeve E. These collars are secured to the bar 31", at a suflicient distance apart for the bar to slide a short distance through'the sleeve before operating the lever l, and thus time the movementof the latter relatively to that of arm A", as to have the latter commence to descend with the templet before the lever-Z, commences to expand the templet-plates, and to have the said lever operate to draw inwardly the templet-plates be fore the arm A commences to rise and re move the templct from off the table. When the bar b, is heirercciprocated horizontally, the outer en! of the lever Z is operated to move back and forth and thus to operate the disk on its pivotal connection to move outwardly and. draw inwardly the tem'plet plates. These collars a, a", are'adapted to adjustably connect with the bar b'flby means not shown, there being one of them at each side of the sleeve E, at such distance apart as will give to said sleeve E, slide-pin U and lever Z, the proper measure of movement required to operate the templet disk-wheel D and provide for an interval of rest between the expanding and indrawing of the templetplates at each reciprocation of the bar If. The letters Z designate a collar and jam-nut arranged on the bar 1) outside of one of the frame-parts F and the letter Z", designates another collar and jam'nut arranged on the bar 17 inside of the adjacent yoke-arm.

The letters A, designate the templet arm by which the templet is operated to descend onto, and to rise from off the bed B This arm connects with the templet top-plateH, at the top of the latter which is attached to the stock )5, above the disk-wheel D and the lever 1", connecting with the latter. From where the arm A donnects with the templet top-plate H, it is extended rear- .ends, connect.

with the yoke Y. This yoke Y, at y and y, journals on the bar I), so as to oscillate thereon, and the arm A where extending beyond the yoke is provided with a segment S, made with a groove in its outer surface,

and the letter designates a chain connecting with said arm in front of the segment, and from where thus connected this chain is arranged within the groove y, and extended downwardly to connect with a spring M with the lower end of the latter connected to the cross-bar f of the frame F, as shown at Fig. 1, or with the chain connecting with the spring, M, and the latter at its lower end w ith the floor of the room in which the machine isplaced by means of the rod 1"" as shown at Fig. 2.

The'letter T designates an arm which is rigidly connected to the yoke Y, at one end of the latter, and this arm is rovided with a depending leg L which adjustably connects with the arnr'l, by means of a setscrew a as shown at Fig. 5.

The letters K designate a cam which is rigidly attached to the wheel w on the camroller shaft 5'', so as to move with the latter whenactuated, and when the latter is rotating and the cam K comes in contact with the depending leg L it will raise the latter and thus force downwardly at the front the yoke Y, connected arm A, lever Z and the templet with the latter resting on the bed B When the engagement of the cam K and the log L ceases, active to raise the arm A and templet from oil the bed. I

.The letters J designate the 'pressers, the function of which is to bear down 11 )on the infolders I I, 1 I and operatc,.t iem to lo descend upon the infoldsmade in the blanks between the infolders and the heated bed. These pressers J, consist of vertically placed bars which at their lower ends are attached are arranged to pass loosely through vertical openings made in the bed, and at their upper ends each of these pressers is providedwlth a 'headh", which overhangs the infolders.

The letters f designate the openings 5 formed in the bed for the passage of the presser-bars J, and their vertical movement therein; and the letters F designate the frame with which these bars J, at their lower horizontal top-plate 7', from the upper sur face of which the bars J, are upwardly projected. This plate 3', at each of its ends, connects to the topgia \l-form end-plate 7' of which there isone and the letters 7', designate a passage-way made in the said frame top-plate.

' The letters B", designate a horizontal. bar which at each of its ends connects with one of the frame end-plates 7' and. the letters M 130 iii then the spring M becomes 10o to a presser frame beneath the bed, and they 1 In This frame consists of 12o each end of the frame; 125

- which at its front end pivotally connects with the depending bar I), and from this con nection it asses rearwardly to rest on the bar B and therefrom in curved direction to terminate in the horizontal end-part j". The letter K designates a cam arranged upon the shaft 8, with the rear end of this lever 3', so positioned that it will be depressed at itsrear end by its engagement with said cam K", and thus bear downwardly on the bar B, against the force of the springs M and thus pull downwardl the )resser-frame F, and cause the heads ll of the pressers J, where overhanging the infolders, to press downwardly upon the latter and thus fix 2 the infold; andwhen this engagement of the lever j, and the cam K, ceases, the springs M become active to raise the presser frame and the pressers J from off the infolders. This lever 7' is 'ointed at n and made to tongue into a b ock m, by which the rear end of the lever may be raised or depressed to regulate the measure of engagement which the end of the lever 7'" makes with the cam K, with the parts thus adjusted held in place'b the set-screw t.

Thefetters T designate a foot-treadle,

which has a fulcrum pivot at h", and at itsrear end, it pivotally connects with the lower end of the rod 1*, and the latter, at its upper end, piiivotally connects with another lever ch is centrally pivoted at h to the 'machine frame, and at its rear end this lever N pivotally connects with the lower end of the clutch -shoe-bar h. This latter is arranged to move in a vertical slide-way t, ar-' ranged on the machine frame at its rear, and

at its upper end to connect with the crescentform shoe h having a cam or incline i upon one of'its u wardly projected ends. As thus constructe when t e foot-treadle is pressed downwardly at the front, its connections with the shoe-bar V, will cause the latter and its connected shoe to descend from out of the groove 9 made in the face of the wheel V2 which latter is'keyed to the cam-roller shaft S and when the treadle is not pressed down,

- the bar If and shoe it? will enter the groove 9*. The letter E designates the gland-pin whic is arranged in a recess or slide-way e,

formed in the wheel'W in a line parallel to the shaft on which the wheel turns, and this pin is provided with a s ring at one of its ends within therecess ass own at e, against the recoil force of which this pin is moved inwardly in its recess. This pin has an ofi'se't wheel, the cam-roller shaft and its connecearner end, which enters the groove g with its other end passing through the side of the wheel W so as to enter one of the spaces between the teeth t' of the clutch-wheel C and this pin is held in engagement with the serrated 7c side surface t of the clutch-wheel C by means of its spring 0 which latter forces that end of thegland-pin which is opposite to the one whereat is located the spring 6 and to pass through the slideway in the wheel W to enter one of the recesses between two of the teeth of the clutclnwheel, as shown at Figs. 8, 9, IO and 11. This clutch-whcel C is formed on the inner side face of the gearwheel G running loosely upon the camroller shaft S which meshes into the pinion G on the driving-shaft S. As thus constructed and adapted to connect, when the gland-pin isin engagement with the clutchtions are operated, and when the gland-pin is forced out of its engagement with the clutch wheel, the cam-roller and its connections are at rest; and each time the foot-treadle is do" pressed and the pressure upon it released, the

machine makes one complete revolution of the cam-roller and its connections, and then the can1roller and its connections come to a rest to be again started by the depression of the foot-treadle, after which the mechanism is again started to complete the infolding of the blank, when the latter is removed from the bed and an unfolded one placed thereon.

The letter X designates a switch-cam having two cam grooves connecting by a switch, loll and formed in the perimetral face of the wheel W", mounted upon the cam-roller shaft, so as to turn with it, as shown at Fig. 3. The letter K designates a traveler or slide-pin arran ed to run in said grooves, when the whee in which they are formed is rotated and in its movement when passing through the switch to pass from one groove to the other. This traveler or slide-pin is projected downwardly from the outer end and under side of an arm a extended laterally from a carrier x, which at its inner end is sleeved on to the sliding-bar bflso as to move back and forth thereon as actuated by i the movement of the traveler or slide-pin in 1 l 5 the switch-cam-grooves.

The letter 2: designates a link which at one of its ends is pivoted to the carrier rs", and therefrom is horizontally extended to connect with the top of-the catch-ring C as no shownat Fig.6, by which connection as the traveler or slide-pin in its movement within the switch-cam groove alternatingly passes by the switch from one of them into the other, the catch-ring is reciprocatingly rotated in its annular slide-way S, formed in the bed 35 I When the catdi ring J is moving in the direction indicated by the arrow 3, of Figs. 4.

and 6, the catches c 0 each engage with one of the latches U, if, of which-there isone of them mounted upon each of the segments AKA", which operate the iufolders P. l, to detain them, and at the same time to unlatch from oil the cat('lu. s a, e, the latches If, U, of which there is one mounted upon each of the segments A. A, which operate the infolders I, l, and when the catch-ring is reversed in dircwtion as indicated by the arrow 4, of Figs. 4 and 6; the operation of the latches and catches is reve'rsml.

The letter 11 designates a sleeve arranged upon the sliding-bar between the two collars a, a; and the letter at, designates a bar which pivotally connects with the underside of the segment-ring lltat one of its ends, and at its other end to the sleeve 1 5, and by which connection as the bar I)" is actuated to slide back and forth in its slide-ways n, 1/, the segmentring R is reeiprocatingly rotated in its annular slideway S From the foregoing description it willnhe seen that the shafts S and S or eitherot them, may be considered as a single means or a single part for effecting an v two or more of the various operations, as those of infolding, pressing, shifting the catcha'ing, lowering and raising the tcmplet, and expanding and. contracting the plates thereof. 'lhecatchring (I is in effect a controller, by the shifting, or reciprocating of which, one or more of the cams which actuate the infolders are attached or detat'hed, so that a part of the infolders will he operative, while others are rendered inoperative, so that a part, of the infolds of the blanks may be formed in one revolution of the shaft 8 and the remaining infolds formed subsequently.

I do not wish to confine myself to mechanism which will com wlete the infolding in two operations, as it is ()l)Vl()US that in some forms of blanks, there may he required three or more successive operations to obtain the desired result. Nor do I wish to confine myself to a shaft 5*, which stops after a single.

rotation, as identical results are obtainahle h a greater or less amount of rotation, by suitable changes.

While at one of the periods of rest, and when the shaft S is-stationary, a blank 'is laid upon the bed in the space between the infolders/and with what is its inner face when made up uppermost. The foot-treadle is then depressed at thefront which releases the ghoul-pin, thus making active itsspring' to connect the clutch (I and operate the shaft 5 to turn as hefore descrihed. On the. init'al movement of the shaft S the templet arm A and the connecte'l temple-t 'l, are actuated to descend u ion the bed with the templet-plates expanded by the lever Z and shnultaneously with the movement of the templet arm and teniplet, the catch'ring C is actuated to make t 1e advance ino-ven'ient of its reciprocation to latch the segments A,

and in hnmediate sequence the segment-ring ll, while making the advance, half of its re ciprm-atiou-acts upon the segments A A latched to the latter to move inwardly the iufoldcrs l, l, so as to carry the subtending s of the illauk over the two ends and one side of the expanded ten1pletplates; after the foreg ing has l1een accomplisl'ied the plates of the templet are drawn inwardly and the presses .l are actuated to descend upon the infolders to press the infolds between the infolders and the bed, and to then rise when the templet-arm and teinplet are raised from off the bed and the infoldelrs V, 2 are moved outwardly and the shaft S" becomes stationary with the blank upon the bed having an infold formed u )On its two ends and one side. To complete the formation of the infolds upon the form of blank thus illustrated, the

foot-treadle is again depressed at the front and mow'ement given to the shalt S and its connections by which the tem )let-arm and 'tei'nplet with its plates e.\'pan( ed again descends upon the blank, while the catch-ring making its return movement latches the segments A A and operates to unlatch the. segment A, A, while the segmenbring R operates the segments A, A, to move inwardl the infolders I, I, to carry the unfoldeif and bottom subtending edge of the blank over the templet-plates thereat. This having been done, the templet-plates are.

drawn inwardly with their inward movement succeeded by the descent of the pressers J. Succeeding the movementof the .pressers, the infolders I, l, are moved outwardly, and the templct-arm and templet are again actuated to rise from oil' the blank, when the latter is removed from the hed. As thus i11 folded the last infold made, and upon that side'of the hlank having rectangular corners, will overlap at the latter the end infolds previously produced. To have the end infolds over the side infold at the rectangular co ners of the blank, the orderin which the infolders act in pairs is reversed.

While I have shownamechanism constructed and arranged to perform the several functions of operating the tenu'ilet-arm and templet to descend on to, and rise from oft a hlank ilaced upon the bed, with means for expanding and indrawing its bottom plates. and a means for actuating a segment-ring to reciprocatingly rotate in an annular slidc wa vyand. to operate segments provided with latcl'ies arranged therein; and means also to operate a catch-ring provided with catches whereby in connection with the segment latches as operated bv the segment-ring the infolders are actuated to move alternatingly in pairs; also a mechanism for operating pressers to desce..d upon and rise from oil the infolders; if desired, the latches upon the segments, the cateh-ring-and- Its catches, to-

gether with the means connecting the same with the driving power, may be dispensed with and the other factors retained without de )arting from my invention.

hile I have illustrated and described a templet provided with expanding and iii-.

drawing plates, having two rounded and two rectangu ar corners, and mfolders having-on their lnner edges a form corresponding to that of the templenplatcs when expanded,

.I do not limit my invention of a means for alternatingly latching and unlatching' the. mechanism operating the infolders to the use of such of the latter and the tcmplet which I have herein shown; inasmuch as the mechanism which I illustrateand describe may be used to operate in substantially differing forms of templets, with the number of the infolders increased or diminished.

To the pressers which I illustrate and describe apart from the means to automatically operate them, I make no claim.

When I use the term die in the claims, I refer to the templet heretofore referred to, composed of a plurality of expanding and contracting plates, which plates may be termed sections.

Wher.in the claims I use the term folding knives, I refer to the parts that have hereinbefore been termed infolders. So, also, the words die and templet are used in the same sense, and the plates of the templet are sometimes referred to as sections. The part 6?, which has been here.- inbefore referred to as a slide bar is in offeet an axle, inasmuch as the templet supporting arm A turns about the bar or axle b as an axis. The templet supporting arm in one or more of the claims I have referred to simply as a support, and as being pivoted on the bar oraxle b. The enlarged portion at the outer end of the templet supporting arm may be designated as a cross-head; and this is the part upon which the templet or die is mounted inorder that the templet or die may be carried upwardly and down Wardly when the supporting arm A is rotated about the axle or bar b upon which it is pivoted. p

The yoke Y forms a convenient means by which the templet supporting arm A may be pivoted iipon the bar or axle 6 The device E hereinbefore called a sleeve, is arranged purpose of expanding and coilapsing the die or templet.

Y \Vhen I use the. term frame in claims 33, l 35 and as, I refer to the swinging member or f templet stock l\' which forms a part of what has hercinbcforc been referred to as a cross- 1 head.- In claim 36 the means cooperating with said templet for receiving and retaining a blank in place for folding refers to that {portion of the bed of the machine which forms a support for the blank.

As further explaining claims 4455, I 1 would say that like the arm A, which carrics the templct, the arm Z (Fig. 7) extends rearwardly from the. templet toward the. axis 1 of swinging. In one aspect there are thus 1 two rearwardly extending arms, the main oneiitted at its rear end for swinging and at its front end rigidly connected to the templet body or stock or frame; while the other is movably connected with the temple-t, having connections for operating the templet plates, and at its rear end has a device. or

relatively to the arm A", preferably but not necessarily a to-and-fro oscillation; at any rate so that its forward end will move or operate a templct plate or plates. This is novel with me, irrespective of the number of movable plates or the timing of the operation thereof, or the precise connection or dearm P, or the form of the arm, or the character of the connection at the rear of arm Z whether or not 'it is automatic, as shown, or the means of operating the machine whether or not by power as shown, or any other details not set forth as requisites in said claims.

I claim and desire to secure by Letters Patent i'sz.
